RIVETING-TOOL.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed May 19, 1919. Serial No. 298,074.

To all whom it may concern:

Be it known that I, EDWIN L. Roonnss, a citizen of the United States, residing at Kenneth, in the county of Rock and State of Minnesota, have invented new and useful Improvements in Riveting Tools, of which the following is a specification.

This invention'relates to tools, particularly to tools used in riveting, and has for its object the provision in a single tool, of a device for holding a rivet while it is being started in position, a device for facilitating the driving on of the usual washer, means for cutting off the rivet in the event that it is too long, and means for barring the rivet after the'washer is placed thereon.

An important object is the provision of a device of this character constructed fundamentally in plier form, the jaws of the pliers serving as nippers for cutting off an excessively long rivet, and the end of one of the members being provided with a recess for burring or upsetting the rivet and also being provided with a hole permitting the passage of the rivet when a washer is driven thereonto.

A further object is the provision of a tool of this character which will be simple and inexpensive in manufacture, highly efficient in use, durable in service, and which will be extremely handy and a labor saver.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the tool,

Fig. 2 is an elevation thereof taken at right angles to Fig. 1,

Fig. 3 is an end elevation,

Fig. 4 is a cross-sectional view on the line H of Fig. 3,

Fig. 5 1s a detail cross-sectional view through the rivet holder,

Fig. 6 is a diagrammatic view of the device showing it in position for the insertion of a rivet in a strap or the like,

Fig. 7 is a view of a rivet projecting through a strap and having a washer engaged thereon and having my device engaged thereon in the process of driving down the washer, and

Fig. 8 is a similar view showing the device in use for upsetting the rivet.

7 Referring more particularly to the drawing, the letter A designates a harness strap or the like, B designates a rivet, and G designates a washer.

In carrying out my invention I provide a pair of members 10 and 11, the former of which is straight and the latter of which is curved and crosses the former. These members are pivotally connected, as shown at 12, and it will be noted that the general construction is that of a pair of pliers. Formed on the end of the straight member 10 adjacent its pivot point 12 is a head 13, at one side of which is formed a blade 1 1 adapted to cooperate with a blade 15 formed at the pivoted end of the curved member 1.1. These blades form nippers whereby rivets may be cut.

Pivot-ally secured upon the straight member 10, as shown at 16, is a rivet holder in the nature of a plate 17 normally lying along the member 10 but disposable when in service to extend preferably at right angles thereto. This plate 17 has secured thereon, as shown at 18, a spring plate 19 provided with a slot 20 adapted to receive a rivet and having a projecting end portion 21 whereby the spring plate 19 may be sprung slightly away from the plate 17 to permit the engagement of the head of a rivet between these plates with the shank of the rivet eX- tending through the slot 20.

Formed in the head 13 adjacent one corner thereof is a cylindrical hole 22 adapted to receive the shank of a rivet, as will be hereinafter described, and formed in the head at another corner is a concavity or depression 23 adapted to serve as a die for upsetting and preferably finishing a rivet after a washer has been placed thereon.

The use of the device is as follows Assuming that an operator wishes to secure together a couple of straps A, he first grasps the projection 21 of the rivet holder and engages the head of a rivet B between the spring plate 19 and plate 17 with the shank of the rivet extending through the slot 20. At this time it should be stated that it is preferable that the plate 17 be swung upon its pivot 16 to extend at substantially right angles to the member 10 so as to be unobstructed thereby. The rivet being thus held its point is placed upon the superposed straps A and a smart blow is struck upon the plate 17 by a hammer or the like to start the rivet. It is then preferable that the operator so move the device that the nipper for cuttingofi the excess upon; the upperend of, the member-10, the

washer C is then driven ho1ne.- If p the. shank of the rivet. then projects too ,far beyond the: Washer; use 1 may be made of the blades 14 and-15 byus ng; the device as a ive length ofthe rivet. V Afterthe-riveti has been properly secured; if it should happen .to{ need 'it,

the device is sopositioned; that the-concavity or :depression 23; is; disposed over the pro-v jecting end ofthe rivet, whereupon by means of;a sharp blow 'upon the upper end of the I handle n1ember110; therivet will be properly burred or; upset upon; the washerr The riveting operationpis thns. completed. From the foregoing description and :a

study ofthe. drawings it will be apparent provided a very simple. and; inexpensive tool by means of which;

that I have thus riveting may be very quickly and easily done in iew of the Vfaet that all" the toolsne cessary forwthe operation are'embodled 1n one simple. compact tool ready'for use in the different operatlons.

-While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I'reserve theright to make such changes in the form, 1
